Ultimate Vocal Remover
What Ultimate Vocal Remover is
Ultimate Vocal Remover (UVR) is a free desktop application that uses deep neural network models to separate audio sources and remove vocals. It supports batch processing and exports WAV, FLAC, and MP3 files. Available stem types include vocals, instrumental, other, bass, drums, guitar, piano, synthesizer, strings, woodwinds, brass, and wind instruments. UVR runs on Windows, macOS, and Linux, and the project says it is open source and free to use and modify. The GUI code is MIT-licensed; developers using its models are asked to credit UVR and its developers. Its core developers trained the included models apart from the Demucs v3 and v4 4-stem models. Windows installation targets Windows 10 or later and should use the main C: drive. The bundled macOS release targets Big Sur and newer, with separate Apple Silicon and Intel downloads; Linux instructions cover Debian- and Arch-based systems. GPU conversion requires at least an Nvidia GTX 1060 with 6GB, while 8GB or more of Nvidia VRAM is recommended. Conversion time varies with hardware, and non-WAV processing requires FFmpeg.
Who it suits
UVR suits people who want a free desktop tool for vocal removal and audio stem separation on Windows, macOS, or Linux. GPU conversions require suitable Nvidia hardware, while AMD Radeon support is limited.
What it does well

Getting started
- Open the project's GitHub page.
- Choose the download or installation instructions for Windows, macOS, or Linux.
- On Windows 10 or higher, install to the main C: drive.
- On macOS Big Sur or above, choose the Apple Silicon or Intel download that matches your Mac.
- For Debian- or Arch-based Linux, follow the repository's manual installation instructions.
- Install FFmpeg if you need to process non-WAV files.
- Use GitHub Issues for help, including detailed reports and error logs when possible.
Verdict
UVR offers free, open-source vocal removal with batch processing and several export formats. Before installing, check the platform-specific requirements and GPU limitations; non-WAV files need FFmpeg.
